This might not be what the game needs the most right now, but I think there's not enough interesting feats to use with melee weapons.
There are like 5 feats in the weaponry skill tree, 3 of them are just buffs to your attacks. So we end up with Circular Slice for swords, and Tremendous Force for Maces. Come on, we need something better than just spinning once with a sword or hitting the ground really hard with a mace! The Pike doesn't even have a usable feat. At least give us 1 more actual feat for each weapon.
Maybe a lunge for the sword where you do a quick jump forward with a stab, inflicting bleed/stun.
An impaling charge with the pike which you can change directions mid-charge, dealing big damage based in distance traveled, maybe even dragging players along like when they're grabbed by lions. (BTW why is the pike's main attack a horizontal slash? Make it a thrust with no forced movement and camera lock like in ARK! Maybe a bit slower for balance).
The mace can have like an uppercut where the user jumps with the momentum of the upward swing, moving a little forward while knocking up/inflicting massive torpor to the target.
Maybe more weapon types would be cool. A lot of icons in the two-handed skill tree represent a two-handed sword being used so I'd really like to see that implemented into a real weapon in-game. The blackjack and Throwing knives have special uses but maybe they should get some love too? I don't really know how tho.
Those are my ideas. All of them have a bit of mobility to help with the rather static movements of most weapons. Hopefully I'm not suggesting something that's too hard to implement.. Sure, they're not historically accurate, but this game wasn't meant to represent historical pirates anyways. You know, with cyclops, magic, undeads and all of that.
If you have anything you'd like to say, feel free to do so .

Considering that so few things can do damage to AoD now (except melee, tames, and a couple firearms), I was shocked to find out that Tremendous Force (a 2-handed Mace melee feat) does absolutely nothing (damage or stun) to the undead.
On PVE especially, what else could this feat even be used for? I have to assume this is an unintended side-effect of the nerf to damage against AoD, probably because the attack is classified as something special.

Devs,
You guys and gals are doing an amazing job and the game is getting better every patch.
Bar the obvious ongoing lag fixes and server optimization changes (planned and in development) - I would like to suggest the following
Would be interesting to get the communities feedback on the following:
1) Climbing onto raft - Press E near to a raft and have a climb animation to get onboard from the ocean
2) add some movement to the lower body in the axe / pick and scythe animations - the current animation looks really janky and Minecrafty compared to others in the game - given the amount of time gathering this would be a nice change for sore eyes and I believe encourage other players to try the game - this has been cited as generic etc.,.... by friends as I have tried to get them to join.
3) Melee combat - This feels too slow - the animations and control just feel like we are in molasses - It would be nice to be able to swing faster - providing more interactive and action based combat - if we can get close to the combat seen in Conan Exiles - this would add a huge advantage to the games long term success and enjoyment.
4) Jumping - the animation seems to have been tweaked but need work still to match the quality of ships etc,
5) Rolling - a roll would be good and add fluidity to combat and animations for falling and dodging. The dodge animation would be great if we turned the body as well as move to the side.
6) Grab - A grab to mantle rocks would be amazing - thinking PUBG style / vaulting.
7) Dagger weapon class would be great :)
8) Bow - the 3rd person view when using the bow looks weird - 1st person much better - would be good to polish look to make it a look more realistic..
I am sure not all at the top of your list but is there is a way to add would be great.
Loving the game and its huge potential - Thank you.
(Feedback on any plans from the devs around these types of things would also be great :) )
Jolly Rodger.

I would like to see a Boxing Ring that could be put up and taken down at Captains leisure. It should allow melee combat between the Crew members and give some sort of experience related to Melee Combat. On long trips this would be valuable in keeping morale up in the crew. I do not have the knowledge to create a mod that would allow this but I have hope someone will see this and go with it ! Maybe the Ring could aso double as a respawn point that could be put up as Combat approaches...?
